Answer: 20°, 50° and 90°
Step-by-step explanation:
From the question, we are informed that the measures of the three angles whose sum is 160 are in the extended ratio 2:5:9.
The exact angle measures will then be:
= 2/(2+5+9) × 160°
= 2/16 × 160°
= 20°
= 5/(2+5+9) × 160°
= 5/16 × 160°
= 50°
= 9/(2+5+9) × 160°
= 9/16 × 160°
= 90°

<span>1. </span><span>The ratio of a wire that is cut
in to 2 is 5:9
The longer piece was 25cm. Now, find the total length and the length of the
shorter wire.
=> 5 : 9 = x : 25
=> First, let’s convert it to fraction
=> <u>5 </u>=<u> 9
</u> x 25
=> 25 (5) = x (9)
=> 125 = 9x
=> 125 / 9 = 9x / 9
=> 13.9 = x
Thus the ratio is approximately 5 : 9 = 13.9 : 25 </span>
Answer:
Step-by-step explanation:
Given
A cube is rolled 84 times
2 occurred 12 times
Experimental probability is determined by the use of data obtained in the experiment.
Therefore, the experimental probability of obtaining 2 on 84 rolls of the die is
